Problems solved by technology

[0002] In the existing technology, there are two types of motors, one is a lithium electric motor with gears, which has a large torque and low efficiency, and the service life of the motor is shortened because the gears are wearing parts; the other is a lithium electric motor with an iron core There are 36 slots on the diameter of 147mm, which is more convenient and has a long service life, but the small torque makes the motor efficiency low
The small motor torque makes the motor unable to climb slopes, and it starts slowly when the load is heavy, which is inconvenient to use

Embodiment Construction

[0014] Such as figure 1 , 2 As shown in and 3, the present invention creates a high-efficiency energy-saving lithium electric vehicle motor, which includes a stator core and a rotor magnetic steel aluminum wheel with a magnetic steel 4. The stator core includes a bracket 1, a silicon steel sheet 2 and a groove 3. The diameter of the stator core is 147 millimeters, and the outer surface of the support 1 is covered with superimposed silicon steel sheets 2, and the outer periphery of the silicon steel sheets 2 is stacked with the groove 3, and the groove 3 is 20 Seven pieces; the rotor magnetic steel aluminum wheel is sleeved outside the stator core, and the rotor magnetic steel aluminum wheel is surrounded by matching magnetic steel 4, and the matching magnetic steel 4 is thirty pieces.

[0015] The working process of this example: the slots 3 on the iron core are reduced so that the space in the slots 3 is larger, more windings can be wound, and the electromagnetic power is in...

Abstract

The invention provides an efficient energy-saving lithium-ion electric vehicle motor which comprises a stator core and a rotor magnetic steel aluminum wheel. The stator core comprises a support, silicon steel sheets and grooves, the diameter of the stator core ranges from 138 mm to 154 mm, the support is sleeved with the superimposed silicon steel sheets, the grooves are formed around the superimposed silicon steel sheets, and the number of the grooves is twenty seven. The stator core is sleeved with the rotor magnetic steel aluminum wheel which is formed by magnetism-provided steel in a surrounding mode, and the number of the magnetism-provided steel is thirty. The efficient energy-saving lithium-ion electric vehicle motor has the advantages that the technical scheme is adopted for enabling the diameter of the stator core of the motor to be 147 mm, the number of the grooves in the stator core is decreased, space in the grooves is large, more windings can be wound, the electromagnetic power is improved, the motor torque is accordingly improved, the efficiency is improved, the service life is prolonged, operation is convenient to achieve, and the efficient energy-saving lithium-ion electric vehicle motor has the advantages of being simple in structure, convenient to maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle motors, and in particular relates to a high-efficiency and energy-saving lithium battery electric vehicle motor. Background technique [0002] In the existing technology, there are two types of motors, one is a lithium electric motor with gears, which has a large torque and low efficiency, and the service life of the motor is shortened because the gears are vulnerable parts; the other is a lithium electric motor with an iron core There are 36 slots on the diameter of 147mm, which is more convenient and has a long service life, but the small torque makes the motor efficiency low. The small motor torque makes the motor unable to climb slopes, and it starts slowly when the load is heavy, which is inconvenient to use. Contents of the invention [0003] The problem to be solved by the invention is to provide a high-efficiency and energy-saving motor for lithium-ion electric vehicles, which ...
